Roberts, Anniston, Ala.Application October 1, 1953, Serial No. 383,605 6 Claims. (Cl. 139-195)This invention relates to a selvage loop retainer for looms and has foran object the provision of a device of the character designated whichshall be simple of design, embodying a minimum of parts, easily appliedto a loom, and effective in operation, whereby cloth woven on a loomhaving my invention applied thereto may have filling the same length orlonger than the spread of the watrp yarn in the reed, and which will lieflat when spread ou Briefly, my invention comprises a retainer wiresuspended from the lay of the loom and passing freely through a guidetube pivotally mounted on the loom temple whereby to rock to and froresponsive to movements -of the lay and alternately place the retainerwire alongside the warp ends in position to engage and retain the loopof filling as the shuttle is thrown, and withdraw the wire duringbeating up movement of the lay.

A particular feature of my invention is the provision of means wherebythe loop of filling is engaged by the wire at a slight distanceoutwardly from the selvage edge of the cloth and the wire, together withthe loop of filling, is drawn inwardly toward the selvage by the tensionof the filling when the shutttle is thrown. By reason of this provisionthere is no necessity of doubling the warp ends at the selvage and thecloth at the selvage is no thicker than it is away from the selvage.

Apparatus embodying features of my invention is illustrated in theaccompanying drawing, forming a part of this application, in which Fig.1 is a side elevational View showing my improved device mounted on theloom temple, with the lay in its extreme backward position, and theretaining wire in position to engage the filling;

Fig. 2 is a similar view showing the lay in extreme forward positionwith the retaining wire moved out of the path of the filling;

Fig. 3 is a plan view showing the retainer wire in position for engagingthe filling; and,

Fig. 4 is a similar view showing the position of the retainer wire afterthe shuttle has been thrown.

Referring to the drawing for a better understanding of my invention Ishow a lay embodying a lower frame member 10 and an upper frame member,or reed cap 11, carrying the usual reed 12. At 13 is shown a loom templewhich, as is well understood, is mounted upon a stationary part of theloom, not shown. It is also understood that a temple is mounted on eachside of the loom and that it is only necessary to show one in order toexplain my invention.

Secured to the upper frame member 11 of the lay, by

. any suitable means, is a guide rod 14, which, as shown,

extends parallel with the upper frame member 11 and forwardly thereof.Freely suspended by means of a loop 16, from the guide rod 14, is aretainer wire 17 which, when the lay is in the position shown in Fig. lof the drawing, extends downwardly below the level 18 of the cloth inthe loom, alongside the selvage ends. The wire 17 extends through aguide tube 19 which is hinged at 21 to a plate 22, secured to the templeby means of the usual temple cap bolt 23. The tube 19 is free to rock toand fro responsive to the to and fro motion of the lay. As shown inFigs. 3 and 4, the guide tube 19 is in the form of a right triangle incross section, the base of the triangle lying in a plane transversely ofthe loom and with the hypotenuse of the triangle adjac the selvage ends24 in the loom.

Thus, when the guide tube is rocked forwardly by the forward motion ofthe lay, the inclined side 20 of the tube, when engaged by the retainerwire 17, causes the wire to move laterally to the position shown in Fig.of the drawing. As can be seen from Fig. 3, when in this position, thewire is spaced a slight distance outwardly of the selvage ends 24 andengages the filling 26, 3

Wl'ien the shuttle is thrown across the loom, the loop of filling 26,engaged by the lower end of the wire 17 is 2,700,400 Patented Jan. z5,iss

drawn with the wire toward the selvage ends to the position shown inFig. 4 of the drawing. As the wire 17 is withdrawn to the position shownin Fig. 2 by forward motion of the lay, the filling is drawn in toprovide a smooth selvage and a cloth of uniform width.

From the foregoing, it will be seen that the position of the retainerwire 17 is controlled by the position of the guide tube 19 and that thelatter is governed by the position of the temple 13. Due to the fewmoving parts of my improved device, it will be apparent that it may beso set as to provide any desired form of selvage.

While I have shown my invention in but one form, it will be obvious tothose skilled in the art that it is not so limited, but is susceptibleof various changes and moditications without departing from the spiritthereof, and I desire, therefore, that only such limitations shall beplaced thereupon as are specifically set forth in the appended claims.

What I claim:

1. In combination with a loom including a lay a temple and a guide rodmounted on the forward side of the lay, a selvage loop retainercomprising a tube pivotally mounted on the temple alongside the warpends, a retainer wire extending downwardly through the tube, means tosuspend the retainer wire substantially vertically from the guide rodwhen the lay is in its backward position to engage the selvage loop andto be moved upwardly and forwardly away from the warp ends duringbeating up movement of the lay.

2. In combination with a loom including a lay a temple and a guide rodmounted on the forward side of the lay, a selvage loop retainercomprising a wire suspended freely from the guide rod alongside the warpends in position to engage a loop of filling as the shuttle is thrown, aguide tube for the wire pivotally mounted on the temple, said guide tubebeing triangular in cross section whereby to cause the wire to shiftlaterally away from the warp ends during beating up movement of the layand to be moved laterally toward the warp ends when the shuttle isthrown.

3. In combination with a loom including a lay and a. temple on each sideof the loom mounted on a stationary part for holding the cloth, a guiderod mounted on the forward side of the lay, a selvage loop retainercomprising a wire suspended freely from the guide rod at each side ofthe loom rearwardly of the temple in position to engage a loop offilling as the shuttle is thrown, a guide tube for the wire pivotallymounted on the temple alrlid free to rock to and fro responsive tomovements of t e lay.

4. Apparatus as defined in claim 3 in which the guide tube is ofrelatively greater cross section than the wire to permit lateralmovement of the wire in the tube during rocking movements of the tube,and in which the tube is triangular in cross section whereby to effect alateral outward movement of the wire during beating up movement of thelay.

5. In combination with a loom having a lay with a guide rod mounted onthe forward side thereof, and a temple having a burr and a burr housingthrough which the outside warp ends pass, a tube pivotally mounted onthe temple alongside the burr housing, and a retainer wire dependingfrom the guide rod and extending downwardly through the tube alongsidethe warp ends when the lay is' in its backward position and disposed tobe moved forwardly and upwardly above the warp ends when the lay movesto to its forward position.

6. In combination with a loom including a temple and a lay, a selvageloop retainer comprising a tube pivotally mounted on the templealongside the warp ends, a retainer wire extending downwardly throughthe tube, means to suspend the retainer wire substantially verticallyfrom the lay alongside the warp ends when the lay is in its backwardposition, to engage the filling, and to be moved upwardly and forwardlyaway from the warp ends during beating up motion of the lay.
